ELECTRIC GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 349,533, datedSeptember 21,1886.

Application filed February 1S, 1886. Serial No. 192,468.

To (LZZ whom it may concern:

Be it known that I, ADoLrn T. SMITH, a citizen of the United States,residing at New York, in the county and State of New York, have inventednew and useful Improvements in Electric Gas-Burners, of which the following is a specification.

This invention consists in the construction of the insulated burner,substantially as hereinafter specified.

In the accompanying drawings, Figure 1. is a side elevation, partly insection, ofan electric gas-burner containing my invention. Fig. 2 is aside elevation, partly in section, of a modification. Fig. 3 is a sideelevation, partly in section, of a modification.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates a body, pillar, or gasway of agas-burner. In the case of electric gas-buQners this body or pillar isfrequently made of material which is an insulator or non-conductor ofelectricity. I have found that a good insulating material for thispurpose is paper or papier-mach. This substance (paper or papier-mache)is cheap, and can be readily rolled, pressed, formed, or molded into anydesired suitable or ornamental form.

To attach the pillar A to a gas-pipe a lining or bushing, I3, of metalor other suitable material is attached to the pillar A by means of anysuitable adhesiveas, forexample, plaster-of-paris; or said bushing canbe screwed to the pillar or attached in any other suitable way. ,Eyproviding the lining or bushing 13 with a screw-thread, .I, the liningor bushing can be screwed onto a gas-pipe.

By providin the pillar or body A with a suitable tip or nipple, G, fromwhich the gas issues, any suitable flame is obtained-as, for example,abats-wing flame, or a iislrtail llame, or other desired form of flame.

The tip or nipple C can be made of lava, metal, or other suitablematerial. The tip can be held in place either by being screwed in orfitted in place in any suitable manner.

The electrode Dis attached to the burner in any suitable manneras, forexample, by clamping the same about the body or pillar A,or in any othersuitable welll;nown manner. If the tip 0 is made of a conductor ofelectricity (No model.)

as, for example, certain kinds of metalthe electric spark can be made tojump from the electrode 1) into the tip 0. The tip 0 thus serves as oneof the electrodes. By attaching a conductor, F, to the tip or electrode0, as seen in Fig. 1, the electricity can be carried ofi'to ignite thegas-jets from other burners.

In case the tip 0 is made of material which is a non-conductor ofelectricity-as, for example,lavaan electrode, E, has to be applied. Thiselectrode E may be applied in various ways. For example, in Fig. 2 theelectrode E passes through a hole or perforation in the tip 0, andpasses through the interior of the tip G into contact with a conductingbushing, sleeve, or collar G. The collar can be attached to the pillar Ain any well-known manner-as, for example, by plaster-of-paris or byscrewing. By attaching the conductor F to the collar G the electricitycan be led off as desired.

The paper or papieronache pillar or body A can be made of various formsor configurationsas, for example, in Figs. 1 and 2, where the pillar orbody is of considerable length.

Another form of pillar A is shown in Fig. 3, where the pillar A isprovided with a 1101- low or socket, into which fits a shank or stem ofa head, II. By means of glue, plaster-ofparis, or otheradhesive the headII and pillar A can be firmly joined together. The pillar A can rest ona base or support, A, of metal or any other suitable material, or it maybe placed directly on the gas-pipe. The tip 0 can be inserted into thehead II in any suitable well-known manner. The electrodes D and E can beattached to the head II in any suitable manner-as, for example, byscrews or pins. inserting between the head H and pillar A a disk orwasher, I, of suitable insulating 111aterialas, for example, isinglass,porcelain, glass, or lavaa guarddlange is formed which prevents thespark from jumping from the electrodes into the metal part of thegaspipe.

The paper or papier-machc pillar can be colored or ornamented in anydesired manner, or itcan be glazed or enameled or provided with aporcelain sleeve, as in aso-called candle-burner.

To form the pillar the paper or papiermache is either rolled or woundabout asuitable core, the core being withdrawn after the pillar isformed; or the pillar is formed by pressing the paper or papier-mach ina suitable mold. In case paper is rolled about a core, a 5 suitableadhesive-as, for example, gluemust be applied to the paper to preventthe paper from unwinding.

By applying a coat of glazing or a sleeve of porcelain orotherlnon-eombustible material danger of the paper or papier-mach pillarbecoming ignited is averted.

I have found that in the case of gasburners which were heretoforeprovided with asbestus bodies the asbestus' crumbles or disintegratesunder the influence of the heat. This does not occur in the case of myburners provided with a. paper or papier-niach body. \Vith regard toburners provided with lava bodies or insulators, the disadvantage is,that the lava has first to be turned or formed and then perforated ordrilled, and finally baked to bring it into a condition proper for usein gas-burners. This proceeding is quite different from the manufactureof my burner, in which the paper or papier-niach provided with anadhesive is simply rolled or molded, and upon drying said paper orpapier-mach body is at once ready for use.

What I claim as new, and desire to secure by Letters Patent, is

1. The pillar or gasway A of a gas-burner, made of paper or papier-maeh,substantially as set forth.

2. An insulated gas-burner having its insulating-section constructed ofor from paper or 5 papier-lnach, substantially as and forthe purposespecified.

per or papier-mach, provided with an elec- 5o trode or electrodes, andprovided with a guardflange, I, at a point below the electrodes,substantially as set forth.

In testimony whereof I have hereunto. set my hand and seal in thepresence of two subscribing witnesses.
